Hello, I am calculating the hydrogen bond autocorrelation function using g_hbond for O-H---O hydrogen bond in system.
I made two groups 1. O-H atoms numbers 2. two oxygen atoms are interacting with OH bond. I am using default hydrogen bond criteria (donor-acceptor distance 3.5 and angle 30) for calculating the autocorrelation function. I am not getting a smooth exponential plot. I get a small bump in the plot. Attached the autocorrelation plot. Why there is not smooth exponential plot. Nilesh
